Lincomycin is a lincosamide antibiotic that comes from the yeast Streptomyces lincolnensis. Lincomycin has been shown to be active in vitro against the following microorganisms: Aerobic gram-positive cocci: Streptococcus pyogenes and Viridans group streptococci; Aerobic gram-positive bacilli: Corynebacterium diphtheriae; Anaerobic gram-positive non-sporeforming bacilli: Propionibacterium acnes; Anaerobic gram-positive sporeforming bacilli: Clostridium tetani and Clostridium perfringens.
Mechanism of action
Lincomycin inhibits protein synthesis in susceptible bacteria by binding to the 50 S subunits of bacterial ribosomes and preventing peptide bond formation upon transcription. It is usually considered bacteriostatic, but may be bactericidal in high concentrations or when used against highly susceptible organisms.
Rapidly absorbed from the gastrointestinal tract following oral administration. Approximately 20 to 30% absorbed orally in fasting state; absorption decreased when taken with food.
Volume of distribution
Protein binding decreases with increased plasma concentrations. Range, 28 to 86% (average, 70 to 75%). Albumin is not thought to be the primary binding component.
Presumed hepatic, however metabolites have not been fully characterized.
Route of elimination
Urinary excretion after this dose ranges from 1.8 to 24.8 percent (mean: 3 percent). Tissue level studies indicate that bile is an important route of excretion.
The biological half-life after intramuscular or intravenous administration is 5.4 ± 1.0 hours. The serum half-life of lincomycin may be prolonged in patients with severe impairment of renal function compared to patients with normal renal function. In patients with abnormal hepatic function, serum half-life may be twofold longer than in patients with normal hepatic function.
This compound belongs to the class of organic compounds known as proline and derivatives. These are compounds containing proline or a derivative thereof resulting from reaction of proline at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom.
Protein L10 is also a translational repressor protein. It controls the translation of the rplJL-rpoBC operon by binding to its mRNA (By similarity).Forms part of the ribosomal stalk, playing a central role in the interaction of the ribosome with GTP-bound translation factors.
